Description

発明の背景
本発明は活性化血液凝固第X因子を可逆的に阻害して強力な抗凝固作用を示す経口投与可能な新規ベンズアミジン誘導体及びそれらを有効成分として含有する血液凝固抑制剤または血栓若しくは塞栓によって引き起こされる疾病の予防・治療剤に関するものである。適応する前記疾病として例えば脳梗塞、脳血栓、脳塞栓、一過性脳虚血発作(TIA)、くも膜下出血(血管れん縮)等の脳血管障害における疾病、急性及び慢性心筋梗塞、不安定狭心症、冠動脈血栓溶解等の虚血性心疾患における疾病、肺梗塞、肺塞栓等の肺血管障害における疾病、末梢動脈閉塞症、深部静脈血栓症、汎発性血管内凝固症候群、さらに人工血管術及び人工弁置換後の血栓形成、冠動脈バイパス術後における再閉塞及び再狭窄、経皮的経管式冠動脈形成術(PTCA)または経皮的経管式冠動脈再開通療法(PTCR)等の血行再建後の再閉塞及び再狭窄、体外循環時の血栓形成などが挙げられる。
生活習慣の欧米化、人口の高齢化などに伴い、心筋梗塞、脳血栓症、末梢動脈血栓症をはじめとする血栓塞栓性疾患は年々増加する傾向にあり、その治療の社会的重要性はますます高まっている。抗血液凝固療法は、線溶療法及び抗血小板療法とともに血栓症の治療及び予防における内科的治療法の一端を担っている。
従来、血栓形成抑制剤として抗トロンビン剤の開発が行われてきたが、トロンビンは凝固反応の最終段階であるフィブリノーゲンのフィブリンへの活性化を司るばかりでなく、血小板の活性化及び凝集にも深く関与していることから、その阻害は出血傾向をきたす危険のあることが知られていた。また、経口投与でのbioavailabilityが低く、現在のところ経口投与可能なトロンビン阻害剤は上市されていない。
活性化血液凝固第X因子は外因系及び内因系凝固カスケード反応の合流点に位置し、トロンビンよりも上流に位置するため、本因子の阻害はトロンビン阻害よりも効率的にかつ、特異的に凝固系を阻害できる可能性がある[トロンボシスリサーチ(THROMBOSIS RESEARCH)19巻、339−349ページ、1980年]。

抗血液凝固活性の測定
抗血液凝固活性はプロトロンビン時間(PT)測定法を用いて決定した。PT測定は以下に示す通りに行った。すなわち、健常人より採血を行い、3.8%クエン酸三ナトリウム水溶液を10分の1容量加え、遠心操作により血漿を分離した。血漿45μlに評価化合物を含むDMSO溶液5μlを加え、室温で2分間インキュベートした。その血漿溶液を含む試験管をSysmex CA-3000全自動血液凝固測定装置(東亜用電子社製)に設置後、37℃で3分間インキュベートし、Sysmex PT II(東亜医用電子社製、ウサギ脳組織トロンボプラスチン、13.2mM塩化カルシウム)100μlを加えた。PTは同装置により自動測定した。評価化合物の溶液の代わりにDMSO5μlを加えたものをコントロールとし、コントロールのPTを2倍に延長する評価化合物濃度の負の対数値を求め(PT2と略す)、抗血液凝固活性の指標とした。代表的な化合物の抗血液凝固活性を下記表−2に示す。

The present invention is caused by a novel orally administrable benzamidine derivative that reversibly inhibits activated blood coagulation factor X and exhibits a strong anticoagulant action, and a blood coagulation inhibitor or thrombus or embolus containing them as an active ingredient The present invention relates to a preventive / therapeutic agent for diseases. Examples of the diseases to be applied include diseases in cerebrovascular disorders such as cerebral infarction, cerebral thrombus, cerebral embolism, transient cerebral ischemic attack (TIA), subarachnoid hemorrhage (vascular spasm), acute and chronic myocardial infarction Diseases in ischemic heart diseases such as heart disease, coronary artery thrombolysis, diseases in pulmonary vascular disorders such as pulmonary infarction and pulmonary embolism, peripheral arterial occlusion, deep vein thrombosis, generalized intravascular coagulation syndrome, and artificial vascular surgery Revascularization such as thrombus formation after prosthetic valve replacement, reocclusion and restenosis after coronary artery bypass grafting, percutaneous transluminal coronary angioplasty (PTCA) or percutaneous transluminal coronary artery recurrent therapy (PTCR) Later reocclusion and restenosis, thrombus formation during extracorporeal circulation, and the like.
Thromboembolic diseases such as myocardial infarction, cerebral thrombosis, and peripheral arterial thrombosis tend to increase year by year as the lifestyles become westernized and the population ages, and the social importance of treatment is increasing It is growing. Anticoagulant therapy is part of a medical therapy in the treatment and prevention of thrombosis along with fibrinolysis and antiplatelet therapy.
Conventionally, antithrombin agents have been developed as thrombus formation inhibitors, but thrombin not only controls the activation of fibrinogen, which is the final stage of the coagulation reaction, but also deeply activates and aggregates platelets. Because of its involvement, its inhibition was known to be at risk of bleeding tendency. In addition, the bioavailability of oral administration is low, and no thrombin inhibitor that can be administered orally has been marketed.
Activated blood coagulation factor X is located at the confluence of extrinsic and intrinsic coagulation cascade reactions and is located upstream of thrombin, so that inhibition of this factor is more efficient and specific than thrombin inhibition Possible inhibition of the system [THROMBOSIS RESEARCH 19: 339-349, 1980].

Measurement of thrombin inhibitory activity
130 μl of 100 mM Tris-HCl buffer solution adjusted to pH 8.4 is added to 10 μl of the aqueous solution of the evaluation compound, and then human thrombin (manufactured by SIGMA) is adjusted to 2 units / ml with pH 8.4 Tris-HCl buffer solution. 10 μl of the prepared solution was added and incubated at room temperature for 10 minutes. Subsequently, D-phenylalanyl-L-pipecolyl-L-arginyl-P-nitroanilide dihydrochloride (Daiichi Chemical Co., Ltd., S-2238) was adjusted to 0.4 mM with pH 8.4 Tris-HCl buffer. 50 μl of the prepared solution was added, the absorbance was measured, and the initial reaction rate was determined. A control prepared by adding 10 μl of Tris-HCl buffer prepared to pH 8.4 instead of the solution of the evaluation compound was used as a control. Absorbance was measured using a Microplate Reader Model 3550-UV (manufactured by BIO RAD) at a wavelength of 405 nm for 16 minutes at 15 second intervals. A negative logarithmic value of the concentration of the evaluation compound when 50% of the thrombin activity (initial rate) when the evaluation compound was not added was inhibited (abbreviated as pIC50) was used as an index of thrombin inhibition activity. Table 1 below shows the thrombin inhibitory activity of representative compounds.

Measurement of anticoagulant activity
Anticoagulant activity was determined using a prothrombin time (PT) assay. PT measurement was performed as shown below. That is, blood was collected from a healthy person, and 1/10 volume of 3.8% trisodium citrate aqueous solution was added, and plasma was separated by centrifugation. To 45 μl of plasma, 5 μl of DMSO solution containing the evaluation compound was added and incubated at room temperature for 2 minutes. The test tube containing the plasma solution was placed in a Sysmex CA-3000 fully automated blood coagulation analyzer (manufactured by Toa Electronics Co., Ltd.), incubated at 37 ° C for 3 minutes, and Sysmex PT II (manufactured by Toa Medical Electronics Co., Ltd., rabbit brain tissue). 100 μl of thromboplastin, 13.2 mM calcium chloride) was added. PT was automatically measured by the same apparatus. A control was obtained by adding DMSO (5 μl) instead of the evaluation compound solution, and a negative logarithmic value of the evaluation compound concentration that doubles the PT of the control was obtained (abbreviated as PT2) and used as an index of anticoagulant activity. The anticoagulant activity of representative compounds is shown in Table 2 below.
